A girl is celebrating her seventh birthday. Every guest is served one large slice of chocolate cake, a hamburger, French fries, and some oranges. Classify the food groups mentioned above. If one slice of chocolate cake contains 35 g od carbohydrats, 15g of fat and 5g of protein. Compute the kilocalories that each slice of cake contains. Classify all the food groups that form a part of a balanced diet along with their sources.
The observed rate constant(k-observed) for one of the trials was measured to be 0.00400 s^-1. If the concentration of hypochlorite was fixed at 0.134 M, calculate the specific rate constant (k) for the trail.
